We are about to install 2 new blood banks at remote sites to replace existing units. The units are connected to our blood tracking system. I'm wondering if anyone has any advice on how to manage this? Space is limited and we are struggling to develop a plan for installation to allow for appropriate mapping validation and connection to the tracking system whilst still providing an on-site service (including provision of flying squad blood). Is there any guidance on movement of blood banks following mapping - and at what point is the exercise invalidated?
